The measurement of cardiorespiratory responses was done under the condition of level walking and running on the treadmill at various speeds. The mechanical work was calculated from the analyzed movement of the limbs. Total work was given as the sum of the vertical displacement of the center of gravity of the whole body (external work), and of kinetic energy of the limbs (internal work). The subjects were five healthy adult men. As to nearly all the items of cardiorespiratory responses, the results tended to increase as the speed increased, both in walking and running. Mechanical work had the same inclination. Compared between walking and running at a given speed, the results of cardiorespiratory responses and mechanical work in running were greater that those of walking as far as the speed was not faster than 120m/min. It was estimated that the value of O_2 requirement in walking becomes greater than that of running as the speed grows faster than approximately 130m/min. The increase was assumed to depend on step frequency. The maximum value of mechanical efficiency in total work was 55.5%, 63.3% in walking and running, respectively.
